Transcript of Photosynthesis and Cellular Respiration

PhotosynthesisThe process in which the cells of plants and some other organisms use the energy of sunlight to make foodCellular RespirationA process where cells break down sugars to release stored energy *THIS CANNOT HAPPEN WITHOUT OXYGENWhat you should now knowProcessBoth processes are for energy creation. Both use glucose for main process. Cellular Respiration is used by animalsPhotosynthesis is used by mostly plantsSunlight is important to all living organismsCarbon Dioxide, Sunlight, and water are converted into glucose and oxygen in photosynthesisMolecules are broken down in cellular respirationNutrients are converted to energy for cell growth and repairCellular respiration is used by animalsPhotosynthesis is used by mostly plantsSo what are the differences and similarities between cellular respiration and photosynthesis?Photosynthesis and Cellular RespirationProcesses of Energy CreationSunlight provides the energy to make glucose and oxygen from carbon dioxide and water.Stage 1: Chlorophyll traps the energy of sunlightStage 2: Chloroplast uses the energy to change carbon dioxide and water into glucose.The chlorophyll is found in these ThylakoidsChloroplastSee those bubbles? That's the oxidation process!!Food is oxidized and combined with sugars from the foodThe product is energy, carbon dioxide, waste and waterFood for ThoughtPhotosynthesisCellular RespirationDraw this Venn Diagram in your notes and compare and contrast the two processes of energy creationNot all nutrients consumed is for energy. Some is used for growth and repair.The Role of ATP and ADPADP and ATP are both chemicals used for energy production.

ATP- ATP stands for Adenosine Tri-Phosphate, and is the energy used by an organism in its daily operations. After a simple reaction breaking down ATP to ADP, the energy released from the breaking of a molecular bond is the energy we use to keep ourselves alive.

ADP- stands for Adenosine Diphosphate, and is constantly converting back and forth from ADP to ATP. So, it is the by-product of the breakdown of ATP and recycled to make ATP again.
